Ultratop

Eagle ULTRATOP – Aliphatic Polyurethane Protective Topcoat for ULTRAFLEX

Eagle ULTRATOP is a single-component, aliphatic polyurethane resin designed as a protective topcoat for ULTRAFLEX aromatic polyurethane liquid waterproofing membranes. It forms a flexible, continuous and glossy protective film that helps protect the underlying membrane against UV radiation, weathering, abrasion and mechanical stress.

Suitable for exposed flat roofs, balconies, walkways, maintenance strips and areas subject to light pedestrian traffic, ULTRATOP provides a durable, easy-to-clean finish. It is also suitable for private car parks with very light traffic when used as part of the specified ULTRAFLEX system.

ULTRATOP is a finishing and protection layer, not a standalone waterproofing membrane. It should be applied over a suitable, correctly prepared ULTRAFLEX system in accordance with Eagle's installation instructions.

Application Guidelines

1. Substrate and membrane preparation

ULTRATOP should be applied over a fully prepared, dry and stable ULTRAFLEX membrane. Ensure the surface is clean and free from dust, grease, loose material and other contaminants that could affect adhesion. Avoid moisture entering from the substrate through capillary action or wicking.

2. Temperature and weather conditions

Apply in suitable dry conditions. The substrate surface temperature must be at least 3°C above the dew point. The ambient temperature should be at least 10°C. Do not apply where moisture or water is present on the surface or is likely to migrate through the substrate.

3. Application

Apply ULTRATOP in thin, even coats using a suitable brush, roller or airless spray equipment. Avoid applying excessive thickness in a single coat. When airless spraying, use a nozzle of 0.007–0.011 inch and the manufacturer's recommended pressure. Up to 5% pure xylene may be used for airless spray application, where required.

4. Recoating

At 23°C, the manufacturer's stated recoating window is approximately 1–48 hours. Temperature, humidity and site conditions can affect drying and recoating. If this window is exceeded, consult Eagle for the correct surface preparation before applying another coat.

Coverage and Consumption

• Typical consumption: Approximately 150g/m² per coat.
• 5kg tin coverage: Approximately 30m² at the stated yield.
• Application: Apply in thin, even coats.

Actual coverage depends on substrate condition, application method, surface profile and the number of coats required. Allow additional material where the surface is uneven or more absorbent.

Creating a Non-Slip Finish

Where additional slip resistance is required, ULTRATOP can be incorporated into a non-slip finish using suitable silica sand or aggregate.

• Apply a thin coat of ULTRATOP.
• Broadcast the specified silica sand or aggregate into the wet coating.
• Allow the coating to cure as directed.
• Where required, apply an additional thin coat of ULTRATOP to encapsulate the aggregate.

Aggregate selection and application must be appropriate for the intended use and required slip resistance.

Important Application Limitations

• ULTRATOP is a protective topcoat, not a standalone waterproofing membrane.
• Use over compatible ULTRAFLEX waterproofing systems in accordance with manufacturer instructions.
• Not suitable for swimming pools or surfaces subject to permanent immersion.
• Do not apply to wet surfaces or substrates affected by capillary moisture or water migration.
• Ensure the substrate is at least 3°C above the dew point.
• Use suitable respiratory, skin and eye protection during application.
• Airless spray application requires appropriate respiratory protection and precautions against airborne coating mist and solvent exposure.
• Follow the current Safety Data Sheet for handling, storage and disposal.

Frequently Asked Questions

What is Eagle ULTRATOP used for?

ULTRATOP is an aliphatic polyurethane protective topcoat used over ULTRAFLEX liquid waterproofing membranes. It provides UV resistance, weather protection and a durable glossy finish for exposed roofs, balconies and walkways.

Can ULTRATOP be used on its own?

No. ULTRATOP is designed as a protective finish for compatible ULTRAFLEX waterproofing systems. It should not be relied upon as a standalone waterproofing membrane.

How much area does a 5kg tin cover?

One 5kg tin covers approximately 30m² at the manufacturer's stated yield of 150g/m². Actual coverage will depend on the substrate and application conditions.

How long does ULTRATOP take to become touch dry?

The manufacturer specifies a tack-free time of approximately 25 minutes at 23°C. This is not the same as full curing or readiness for traffic.

When can I apply a second coat?

The manufacturer's stated recoating window is approximately 1–48 hours at 23°C. Always ensure the surface is suitable for recoating and follow the technical instructions.

Can ULTRATOP be used on balconies and walkways?

Yes. ULTRATOP is designed for exposed applications including balconies, walkways and maintenance strips, where it protects the underlying ULTRAFLEX membrane.

Can ULTRATOP be used in swimming pools?

No. Standard ULTRATOP is not intended for fully immersed applications. Eagle offers the separate two-component ULTRATOP WR product for swimming pools, ponds and other suitable aquatic applications.
